IPC: B25D9/14
Filed: 1930-09-05
Abstract: 352,310. Percussive tools. INGERSOLL-RAND CO., 15, Exchange Place, Jersey City, New Jersey, U.S.A. Sept. 5, 1930. No. 26529. Convention date, Nov. 27, 1929. [Class 124.] In valveless percussive tools wherein the piston effects the distribution of the pressure fluid which is constantly admitted through a passage V in a plug S to a chamber R in the piston, an annular groove Y in the piston controls the supply to the forward cylinder end through a passage b in the plug and cylinder. A port X in the plug, the groove Y in the piston, and a neck Z in the plug S enables fluid to pass to the rear of the piston. The exhaust ports D, E are controlled by the piston.

Patent GB-1557196-A (GB)
Title: Automatic vending machine
IPC: G07F7/02
Filed: 1976-06-25
Abstract: The apparatus is suitable for self-service shops and supermarkets and serves for simplifying and speeding up the sales transaction. When one or more product items (11) are extracted from the container (10) out of a rack (15), a balance (12') connected to the container (10) determines the difference before and after extraction. A purchase card (T), which can be introduced into an introduction slot (2) of the rack, is used as an unlocking means for opening the door (9) and thus makes it possible to extract the product. Moreover, the purchase card (T) can also serve as a storage means, in that the information relating to the weight difference and to other sales particulars is marked on it. The purchase transaction at the rack (15) is terminated by actuating a statement device (14) and extracting the purchase card (T) from the introduction slot (2). The information is then read off from the purchase card at a pay counter and is fed to a data-processing system, whereupon a bill is made out. <IMAGE>

Abstract: 632,505. Producer-gas. ARNOLD, C. (Standard Oil Development Co.). Sept. 11, 1946, No. 27354. [Glass 55 (i)] A process for the production of producer gas from coal, coke, and like carbonaceous material comprises establishing two separate fluidized treatment zones 1 and 2, maintaining the zone 2 at a temperature between 1500-1800‹ F. and feeding particulate carbonaceous material through the line 28, feeding partly spent carbonaceous material to the zone 1 from the zone 2 through lines 12 and 15 and passing an oxygen containing gas through the zone by a line 17 to maintain a temperature between 2000-2400‹ F by combustion of the residual carbon in the partly spent carbonaceous material to carbon dioxide, passing the combustion gases through lines 7 and 5 to the zone 2 where a reduction of the carbon dioxide to carbon monoxide is effected and feeding the heated residual solids from the zone 1 through lines 20, 23, 25 and 28 to the zone 2 to supply at least a part of the heat required to maintain the desired temperature, producer gas being withdrawn from the zone 2 by lines 8, 10 and 18 passing in indirect heat exchange with the oxygen containing gases fed to the zone 1. An excess of oxygen containing gas may be fed to the zone 1 so that the combustion gases passing to the zone 2 contain oxygen sufficient to supply by partial combustion in the zone 2 any heat required in excess of that supplied by the circulated solids. The temperatures in either zone may also be controlled by the addition of steam. Ash may be withdrawn from the system from the separator 6 by the-line 22 or by blowing the heated residual solids from the zone 1 with a hot inert gas in an enlarged zone 24. Specification 586,391 is referred to.
